Draw Circles and Arcs

You can create a variety of curved objects, including circles and arcs. 

Draw Circles

To create circles, use one of the following methods:

■

Specify the center and radius (default method).

■

Specify the center and diameter.

■

Define the circumference of the circle with two or three points.

■

Create the circle tangent to two existing objects. 

■

Create the circle tangent to two objects and specify a radius.

Draw Arcs

To create arcs, you can specify various combinations of center, endpoint, start point, radius, angle, 
chord length, and direction values. The following examples illustrate three ways to specify two 
points and an included angle.
